SWITCH.

SPECIFICATION forming part of Letters Patent No. 513,935, dated January30, 1894.

Application filed July 26, 1893. Serial 110.481.513- (No model.)

To all whom it may concern.- v Be it known that I, JOSEPH R. J ONES, acitizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Railway-Switches, which improvement is fully set forth inthe following specification and accompanying drawings.

My invention relates to improvements in to railway switches and consistsof the combination and arrangement of parts as hereinafter set forth.

Figure 1 represents a side elevation of a portion of a railway switchembodying my :5 invention. Fig. 2 represents a top or plan View ofanother portion of the same. Fig. 3 represents a top or plan view of thedriver of the switch. Fig. 4 represents a bottom plan view of the slideof the switch, said slide being engaged by said driver.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings: A designates a stand, and B designates alever mounted 2 5 thereon, said lever having two limbs G and D.

E designates a rod which is pivotally connected with the limb C and aclutch F.

G'designates a rod which is pivotally connected with the limb D and aclutch H. Each 0 of said clutchesconsists of an angular or other shapedpiece of metal or other suitable material,the clutch F being mounted onthe traveler J, and the clutch H being mounted on the traveler K, saidtravelers consisting of 3 5 blocks or pieces of metal or other materialhaving serrated or angular sides for purposes hereinafter explained. Thetraveler J is freely fitted on the post L, and the traveler K is fittedon the post M, said posts being 40 supported on the road bed or the baseof the stand A.

N designates a chainwhich is guided on the roller P and passes betweenthe clutch F and the traveler J, and has its upper end sup- 5 ported onand guided by a roller Q, and carrying a weight R.

S designates a chain which is guided on the roller T, and passes betweenthe clutch H and traveler K, and has its upper end supported on andguided by the roller Q and carrying a weight U. V

The chains N and S are connected by the rods N,' S', with the chain V,which passes around the pulley W, and is attached to one end of thelever X, the other end whereof is connected with the driver Y, saidpulley, lever and driver being properly mounted on the road bed.

The driver consists of a sliding bar having inclined faces Z on oppositesides, the same being adapted to engage with shoulders or rollers-A onthe slide B, the latter being connected with the movable rails of aswitch, it being evident that when the driver is operated, it impartsmotion to the slide B and consequently moves the switch rails. Thedriver is also connected with the lever C which is attached by the linkD with the detector bar E so that the operation of the driver willimpart motion to said bar. It will be seen that when the lever B isoperated, the relative clutch is moved so as to force the adjacent chainagainst the teeth or angles on the sides of the traveler, thus tightlyholding said chain The traveler now rises and carries with it the chainas clutched, thus imparting motion to the lever X, the driver Y andslide B, and consequently setting the switch in the open or closedposition as desired. When the lever B is rotated in the reversedirection, the first named chain is released and the other chain isclutched, and thus the switch is operated in the opposite direction andthus closed or opened as desired. It willbe seen that either of thechains passes freely between the respective clutch and traveler, andhangs freely on the pulley Q, whereby it is kept taut by the weight onthe end thereof. Should the chain contract the same rides on said pulleyQ and its weight is overcome. Should however the chain expand due toheat, it will ride on the pulley and have its slack taken up by theweight. A compensation is thus made for contraction or expansion of thechain or chains, due to heat or cold, whereby the chain or chains andconnected parts are relieved of strain, and breakage of the same isprevented.

In describing the chains N and S as such, a portion of the same mayconsist of rods N S without producing different results. In lieu of therods N, S ,I may use pipes, cords, chains or other connections withoutproducing difierent results from those stated. It will also be noticedthat should there be any tampering with the switch, the connections N, Swill be disturbed, and this fact will be communicated to the operator inthe tower or elsewhere, wherein the stand A is located, owing to themovement of the weights R and U, due to such disturbance.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Movable rails with a connecting slide, a driver for operating saidslide, a lever connected with said driver, the pulley WV, the chain Vpassing around said pulley and connected with said lever, the operatinglever B having the limbs C and D, the rods E and G connected with saidlimbs and haviugclutches connected therewith, traveling blocks to whichsaid clutches are pivoted, and chains or rods secured to each end ofsaid chain V and passing between clutches and blocks, and having aweighted end passing over a depending pulley, said parts being combinedsubstantially as described.

2. Movable rails with a connecting slide, a driver for operating saidslide, a lever connected with said driver, a pulley with a chain passingaround the same, and connected with the said lever, separate chainsconnected with the ends of said pulley chain, an operating lever havingtwo limbs, and separate clutch mechanism connected with each of saidlimbs for each of said separate chains, said parts being combinedsubstantially as described.

3. A switch operating mechanism consisting of a driver with the lever X,the pulley W, the chain V around said pulley and connected with saidlever, the operating lever B having the two limbs G and D, clutchmechanism operated bythe movements of said limbs,

and separate chains connected with the'ends of said chain V, and adaptedto be engaged by said clutch mechanism substantially as described, saidparts being combined substantially as set forth.

4. Movable rails with a connecting slide, a driver engaging said slide,a lever connected with said driver, a pulley, the chain V passing aroundsaid pulley and connected with said lever, chains connected with theends of said chains Vand having weighted ends passing over a dependingpulley, the operating lever B with the limbs G and D,and separate clutchmechanism for said weighted chains connected with said limbs, said partsbeing combined substantially as described.
